The Rotterdam Study aims to understand disease causes in the elderly and has found new risk factors and genetic influences on various conditions.

Stem cell offspring help control their parent stem cells, affecting tissue health, healing, and cancer.

The immune system plays a key role in tissue repair, affecting both healing quality and regenerative ability.

The guidelines advise against using testosterone and DHEA in women for most conditions due to safety and effectiveness concerns, but suggest considering testosterone for postmenopausal women with low sexual desire.

TGF-β is crucial for tissue repair and can cause diseases if not properly regulated.

The document concludes that the fast-growing direct-to-consumer genetic testing market lacks sufficient regulation, posing risks to consumers due to questionable test quality and accuracy.

The timing of when the gene Bmal1 is active affects aging and survival, with its absence during development, not adulthood, leading to premature aging.

Eph receptors and ephrins may be promising targets for treating diseases, but more understanding is needed for effective and safe therapies.

Mice lacking the PPARγ gene in their fat cells had almost no fat tissue, severe metabolic problems, and abnormal development of other fat-related tissues.
